Yoon Shi Yoon plays Yoo Hyun Jae, a 1990s top star who travels tot he future (otherwise known as 2017) and ends up entangled with Kim Min Jae's Lee Ji Hoon and his best friend Choi Woo Seung, played by Lee Se Young. Ji Hoon dreams of debuting as an Idol and Woo Seung is masquerading as Ji Hoon at the hagwon to prep to take the civil service exam, since she can't afford the lessons herself. The supporting cast in this drama is just as stellar as the lead actors. Hyun Jae is such a delightful goober, you can't help but root for him. Be prepared for some second lead syndrome (and also to flip flop on who the second lead actually is). Yoon Shi Yoon really embraces the whole fish out of water concept, while still embodying the kind of confidence one would expect from a (former) top star. It is something of a coming of age story, while not being quite like anything else I've watched. It was really endearing. The pacing can be somewhat problematic, and some of the petty machination stuff got a bit draggy, but all in all, this was a rough little gem that I thoroughly enjoyed.
